WAVE

Application led December My invention relates to improvements in wave motors and has for its object to provide a motor especially adapted for installation in a floating hull and wherein the movement of a rotor, mounted on a circular track carried by such floating hull, and fixed upon the outer end of a driving shaft, imparts power to a driven shaft, through suitable gearing. The connections between the driving shaft l0 land driven shaft are such that the latter will be driven in but one direction regardless of whether the rotor and driving shaft are rotated in a clock-wise or a counter-clock-wise direction.

The motor of my invention is well adapted for use in serving as an auxiliary motor upon sailing ships or in connection with ships driven by other power.

Description.

In the hull A and upon the deck B the circular track C is mounted. Concentrically within the track Cis a trunnion bearing 6 carrying the vertical trunnion 7, on which trunnion 7 the rotating base block 8 is mounted. The block 8 has a central standard 9 in which the threaded sleeve 10 is fixed, as shown, to accommodate the threadedportion 11 of the driving shaft D. The block 8 has at its outer end a standard 12 in which'is journaled the inner end of the driving shaft D. Fixed at the outer end of the driving shaft D, and traveling upon the circular tra-ck C is the rotor E.

Mounted on the driving shaft D yare stops 13 and 14 to limitthe movement of the sleeve 10 upon the shaft D.

The sleeve 10 has fixed at its ends the bevelgears 15 and 16, arranged to alternately MOTOR/'s 12, 1925. Serial No. 74,921.

mesh with the bevel-gear 17 loosely mounted on the driven shaft 18 and arranged to rotate the driven shaft 18 through the rackwheel 19 (fast on the bevel-gear 17) and the pawls 20, carried by the pawl-wheel 21 (that wheel 21 being fast on the driven shaft 18).

By means of the mounting of the sleeve 10 as thus shown and described, the rotation of the rotor wheel E and shaft D, either in clock. wise or counter-clock-wise direction will serve to drive the shaft 18 in one direction, the thread on the shaft D carrying the sleeve 10 back and forth, with the reversal of movement of the rotor E, to alternately engage the bevel gears 15 and 16 into operative engagement with the bevel gear 17.

A fly-wheel 22 is mounted on the shaft 18, as shown, and an armature 23, forming part of the generator, may be mounted directly on the shaft 18 as shown in Fig. 1.

When it is desired to mount the apparatus in a freight or passenger vessel-it may be advantageous to have the track C mounted on an open deck, where the operation of the rotor E may be directed from the bridge of the vessel and the machine brought to rest when necessary. Therest position is secured by means of a standard 24 at the top of which the shaft D may be caught and heldby means of the fork 25, disengagably mounted in the top of the standard 24 as shown in Fig. 3.

As shown in Figs. 1, 4 and .5, the track C may be below or above the fly-wheel 22, according to the particular installation (within the hull A, as in Fig. v1, or upon an exposed deck B, as in Figs. 4 and 5) desired; the moving parts in both cases are identical in function, mode of operation and result.

The mechanism employed in practising my invention may be varied in structure without departure from my actual inventive concept as defined by the appended claims.
